Anomalously low magnetic damping of a metallic ferromagnet

May 16, 2016
Author(s)
Justin M. Shaw, Martin Schoen, Danny Thonig, Michael L. Schneider, Thomas J. Silva, Hans T. Nembach, Olle Eriksson, Olof Karis
The phenomenology of magnetic damping is of critical importance to devices which seek to exploit the electronic spin degree of freedom since damping strongly affects the energy required and speed at which a device can operate. However, theory has struggled

A New Regime of Pauli-Spin Blockade

April 7, 2016
Author(s)
Justin K. Perron, Michael D. Stewart, Neil M. Zimmerman
Pauli-spin blockade is a phenomenon that allows for a type of spin to charge conversion often used to probe fundamental physics such as spin relaxation and singlet-triplet coupling. In this paper we theoretically explore Pauli-spin blockade as a function

Effect of Hierarchical Cluster Formation on the Viscosity of Concentrated Monoclonal Antibody Formulations Studied by Neutron Scattering

January 21, 2016

P. Douglas Godfrin, Isidro E. Zarraga, Jonathan Zarzar, Lionel Porcar, Peter Falus, Norman J. Wagner, Yun Liu
Recently, reversible cluster formation has been identified as an underlying cause of anomalously large solution viscosities observed in some concentrated monoclonal antibody (mAb) formulations. As high solution viscosity prevents the use of subcutaneous

Heat transfer principles in thermal calculation of structures in fire

November 1, 2015
Author(s)
Chao Zhang, Usmani Asif
Structural fire engineering (SFE) is a relatively new interdisciplinary subject, which requires a comprehensive knowledge of heat transfer, fire dynamics and structural analysis. It is predominantly the community of structural engineers who currently carry
